Study information

Scientific title

Phase II trial of alemtuzumab, dexamethasone and lenalidomide followed by randomisation to lenalidomide maintenance versus no further treatment for high-risk CLL (NCRI CLL210)


CLL210 (CamDexRev)

Study hypothesis

All patients will receive induction therapy for 24 weeks with alemtuzumab, dexamethasone and lenalidomide (CamDexRev). Patients with stable or progressive disease (SD/PD) will receive no further trial treatment and will be managed at the discretion of local investigator. Patients who achieve a CR or PR may elect to have an allogeneic stem-cell transplant. Those responders who decide not to have a transplant will be randomised between continuing lenalidomide until disease progression or receiving no further trial treatment.
Primary:CR rate after 6 months of induction therapy
Progression-free rate after 2 years of maintenance therapy, defined as the proportion of patients who are progression free and alive at 2 years
Overall, complete and partial response rates following induction therapy
Minimal residual disease (MRD) negativity rate following induction therapy
Overall survival (time from start of study treatment to death)
Progression-free survival (time from initiation of study treatment to progression or death)
Time to treatment failure (time from initiation of study treatment to treatment failure defined as progression, death or initiation of alternative treatment due to failure to achieve CR or PR)
Duration of response (time from first achievement of CR or PR to first time of progression or death)
Quality of life
Descriptive summary of Progression-free and overall survival among transplant-eligible patients
These will be estimated separately for the induction and the randomised phases of the study.
